I do not limitmy invention to the exact proportions herein described as they may be'varied, as for instance the proportional (but not below fifty per cent.) to permit of an increase of lead or manganese, or the iron can be increased from two to five, or by increasing the ratio of manganese the iron may be dispensed with.

I claim is: V
